Eventually once you figure all this stuff out, and get the chair, controller positioning, and CG, tyres, and programming all perfect then its a totally different chair. And its natural, easy, and highly usable and sort of automatic and predictable.
Then when you get in another stock chair, or a new chair it feels absolutely unusable! Even dangerous. Because it
IS! I tested a lot of other peoples chairs over the years. EVERY stock chair is frankly useless. A few small changes make a massive difference.
And you become very picky and critical like me
And this is the part that leaves me bewildered. I suspect 95 to 99 percent of all powerchair users are in stock, badly programmed chairs, with incorrect cg, seating positions, wobbly mounted, incorrect controller positioning, bad joystick techniques, solid tyres, that are barely usable with evil programming and stupid turn acc/dec settings, and 101 other programming or configuration errors, and they do not even know! If you ask them, everything is just fine! They think their chairs are great! They think WE are nuts.
